Coles objected when Arnott’s, owned by US food giant Campbell Soup, wanted to increase the price of 54 of its products by between 2% and 10%.

The resulting row left Coles without supplies, including Tim Tams, for two weeks in October. When they settled, Coles couldn’t agree on price rises for ten Arnott’sbiscuits and some liquid stock from the Campbell’s range.

“Our average family shopper spends around $150 per week on food and groceries and they don’t have the spare cash laying around to give to Campbell’s-Arnott’s every time they decide to put their prices up,” a Coles spokesman told Business Insider.
